Node.js offers a great environment for building ETL scripts. This is because Node is very easy to program and work with, AND has interface libraries for almost everything under the sun.

We need a framework that makes writing ETL scripts easy:

Supports creation and re-use of components
Cleanly divides input/output concerns from transformation concerns
Works identically in both event-driven and batch scenarios
Supports an easy development/testing mode
Provides good visibility when running in production
Has a simple DSL for expressing transformation logic

Chromium OS is cool. Chromium OS with crouton is cooler. Chromium OS with Docker is even cooler. This is specifically a guide for the Chromebook Pixel 2 (2015), but I can't think of any reason it wouldn't work with other devices.

Create a build environment
Customize the kernel
Build Chromium OS
Flash Chromium OS to USB
Install Chromium OS

Installing Node.js with `nvm` to Linux & macOS & WSL

A quick guide on how to setup Node.js development environment.

nvm allows installing several versions of Node.js to the same system. Sometimes applications require a certain versions of Node.js to work. Having the flexibility of using specific versions can help.

Open new Terminal window.

In this article, I will share some of my experience on installing NVIDIA driver and CUDA on Linux OS. Here I mainly use Ubuntu as example. Comments for CentOS/Fedora are also provided as much as I can.
